Terraforming a planet upgrades its levels, and unlocks new ships for alliance members to buy at the ship factory.

After being upgraded to a "Primordial World," an alliance planet surpases what Earth can provide, and members can buy Dreadnought ships.

Planetary engineering allows players to upgrade and repair items they find inside the game using Black Dollars. Engineering is the same on all planets, and there are no benefits to having a higher planet level.
